Isihloko: Ukuvula amandla e-abaguquli bemvamisa: ukwandisa ukusebenza kahle kanye nokonga izindleko
Isigaba sokuqala: Isingeniso kuisiguquli semvamisa
Isiguquli semvamisa, esaziwa nangokuthiidrayivu yemvamisa eguquguqukayo (i-VFD), iyithuluzi lokuguqula amandla elilawula futhi lilawule ijubane lemoto kagesi. Ngokulawula imvamisa kanye ne-voltage enikezwa emoto, i-frequency converter ingalawula ngokunembile ijubane kanye ne-torque yemoto. Lawa madivayisi aguquguqukayo asetshenziswa ezimbonini ezahlukahlukene, kusukela ekukhiqizeni kanye nezinhlelo ze-HVAC kuya emandleni avuselelekayo kanye nezokuthutha. Kule bhulogi, sizohlola amakhono abaguquli bemvamisa, sixoxe ngezinzuzo zabo, futhi sikhanyise indima yabo ebalulekile ekuthuthukiseni ukusebenza kahle kanye nokonga izindleko.
Isigaba sesibili: Isimiso sokusebenzaisiguquli semvamisa
Isiguquli samaza okushintshashintsha imvamisa kanye ne-voltage ehleliwe yokunikezwa kwamandla okufaka ibe imvamisa kanye ne-voltage elungisekayo, yakha ukuphuma kwemvamisa eguquguqukayo efanele ukushayela izinhlobo ezahlukene zama-motor. Ngokulungisa imvamisa yokufaka, isiguquli samaza okushintshashintsha singalawula ijubane lemoto. I-alternating current engenayo (i-AC) ilungiswa kuqala kusetshenziswa i-rectifier bese iguqulwa ibe yi-direct current (DC). Isekethe ye-inverter ibe isisetshenziswa ukuguqula i-DC voltage ibuyele ku-AC voltage ngemvamisa kanye ne-voltage elungisekayo. Lokhu kukhishwa kwe-AC elungisekayo kufakwa kumoto, okuvumela ukulawula okunembile kwejubane kanye ne-torque yayo.
Isigaba 3: Izinzuzo eziyinhloko zama-frequency converters
Abaguquli bemvamisazinikeza izinzuzo eziningana ezisetshenziswayo ezimbonini ezahlukahlukene. Okokuqala, zivumela injini ukuthi isebenze ngesivinini esiphezulu kunokuba isebenze njalo ngamandla aphelele, okuholela ekongeni amandla okukhulu. Ngokulungisa isivinini ukuze sihlangabezane nezidingo ezithile zomthwalo,abaguquli bemvamisakunganciphisa ukusetshenziswa kwamandla, ngaleyo ndlela kunciphisa izikweletu zikagesi. Okwesibili, zithuthukisa ukulawulwa kwenqubo ngokunikeza ukulawulwa kwesivinini okunembile, ngaleyo ndlela kwandise umkhiqizo futhi kuncishiswe ukuguguleka kwemishini. Ngaphezu kwalokho, i-frequency converter inikeza imisebenzi yokuqalisa nokumisa ethambile, ngaleyo ndlela kunciphisa ukucindezeleka komshini futhi kwandise impilo yenkonzo yama-motor nemishini. Ngaphezu kwalokho, ama-frequency converter aqeda isidingo sokulawula omshini njenge-throttles nama-damper, okwenza kube lula ukuba yinkimbinkimbi kwesistimu kanye nokugcinwa kwayo.
Isigaba 4: Ukusetshenziswa kweisiguquli semvamisa
Ama-frequency converter asetshenziswa kabanzi ezimbonini ezahlukahlukene. Ekukhiqizeni, asetshenziswa emishinini efana nama-conveyor, amaphampu nama-compressor ukuze kusetshenziswe kahle amandla futhi kube lula ukulawula imigqa yokukhiqiza. Ama-variable speed drive nawo ayingxenye ebalulekile yezinhlelo ze-HVAC zesimanje, okuvumela ukulawulwa okunembile kwama-ventilator, ama-chiller namaphampu ukuze kuthuthukiswe induduzo kanye nokusebenza kahle kwamandla. Ezinhlelweni zamandla avuselelekayo njenge-wind turbines nama-solar panel,abaguquli bemvamisazidlala indima ebalulekile ekuguquleni amandla e-DC aguquguqukayo akhiqizwa abe amandla e-AC ahambisana negridi. Ngaphezu kwalokho, ama-frequency converter asetshenziswa ezinhlelweni zokushayela izimoto zikagesi ukulawula isivinini semoto kanye ne-torque, okwenza kube lula ukusetshenziswa kwamandla ngempumelelo kanye nokwandisa isikhathi sokuphila kwebhethri.
Isigaba 5: Izinto okufanele uzicabangele lapho ukhetha i-inverter
Uma ukhethaisiguquli semvamisa, kunezici eziningana okufanele uzicabangele. Okokuqala, isilinganiso samandla kufanele sihambisane nemininingwane yamandla emoto ukuqinisekisa ukuhambisana. Ububanzi bamandla kagesi kanye nemvamisa ye-inverter kumele futhi buhambisane nokunikezwa kwamandla okutholakalayo. Ngaphezu kwalokho, amasu okulawula, njengokulawulwa kwe-vector yamandla kagesi noma ukulawula i-torque eqondile, kufanele ahlolwe ngokusekelwe ekusebenzeni kwemoto okudingekayo. Kubalulekile ukunquma izici zokuvikela ezidingekayo, njengokuvikelwa kwamandla kagesi ngokweqile kanye nokuvikelwa kwamandla kagesi ngokweqile, ukuvikela imoto kanye ne-inverter ekulimaleni okungenzeka. Okokugcina, ukulula kokufakwa, ubungane bomsebenzisi kanye nokutholakala kwezinsizakalo zokusekela abakhiqizi kuyizinto ezibalulekile ngokulinganayo.
Isigaba 6: Imbuyiselo ekutshalweni kwezimali kanye nokonga izindleko
Ngokuhamba kwesikhathi, ukutshalwa kwezimali ku-isiguquli semvamisakungaholela ekongeni izindleko okukhulu kanye nembuyiselo ekhangayo ekutshalweni kwezimali (i-ROI).Abaguquli bemvamisakusiza ekunciphiseni izindleko zokusebenza zesikhathi eside ngokunciphisa ukusetshenziswa kwamandla, ukwenza ngcono ukusebenza kohlelo kanye nokwandisa isikhathi sokuphila kwemishini. Ngaphezu kwalokho, ukulawulwa kwenqubo okuthuthukisiwe okunikezwa ngabaguquli bemvamisa kuqinisekisa ukwanda kokukhiqiza, ngaleyo ndlela kwandise umkhiqizo kanye nenzuzo. Lapho kuhlolwa imbuyiselo ekutshalweni kwemali, kubalulekile ukucabangela izindleko zokuthenga nokufaka zokuqala, kanye nokonga amandla okulindelekile kanye nenzuzo yokukhiqiza phakathi nesikhathi sokuphila kohlelo loguquli bemvamisa.
Isigaba 7: Isiphetho
Ngokufigqiwe,abaguquli bemvamisaziyithuluzi elibalulekile eliletha ukusebenza kahle, ukuguquguquka kanye nokonga izindleko ezimbonini ezahlukahlukene. Ngokulawula isivinini semoto kanye ne-torque, zenza kube lula ukwenza ngcono amandla, ukulawula izinqubo kanye nokuphila isikhathi eside kwemishini. Ngezinhlelo zokusebenza ezisukela ekukhiqizeni kanye nezinhlelo ze-HVAC kuya emandleni avuselelekayo kanye nezokuthutha,abaguquli bemvamisasezibe yingxenye ebalulekile ezinhlelweni zobuchwepheshe besimanje. Ukucatshangelwa ngokucophelela nokukhetha i-frequency converter efanele ngokusekelwe ezidingweni nasezidingweni ezithile kungabangela ukonga okukhulu kwezindleko, ukwanda kokukhiqiza kanye nendlela eqhubekayo yokusetshenziswa kwamandla. Ukwamukela lobu buchwepheshe kuyindlela kuphela yokuthuthukisa ukusebenza kahle, ukunciphisa izindleko, nokudala ikusasa eliluhlaza.
